Makita‘s random orbital sanders are workhorses in UK workshops. The BO5041 in particular is ubiquitous on building sites. If you own one—or are buying one—understanding which pads and discs fit, which third-party alternatives work, and how to maintain your sander will save time and frustration.
This guide covers every Makita orbital and random orbital sander, explains 8-hole pad compatibility with DeWalt and other brands, and shows you where to find replacement pads and abrasives at the best UK prices.
Makita Sander Models and Specifications
Makita’s 125mm random orbit sanders (BO5030, BO5031, BO5041, DBO180) share pad 743081-8; Makita also makes 150mm models.

The Makita 125mm 8-Hole System
Makita’s 125mm random orbit sanders use the same round pad and 8-hole 125mm discs. This consistency is intentional: Makita designed their system to work across the entire product line without exception.
Hook-and-Loop Backing
Every Makita pad uses hook-and-loop (velcro-style) backing. This means:
- Discs attach and remove instantly
- No adhesive residue to clean
- Easy mid-job disc changes
- Low cost per disc change
Dust Extraction
The 8 holes feed Makita’s through-the-pad dust collection, into the dust bag or an extractor.
Makita Replacement Pads
Replacement pads should be OEM parts. Makita pads are engineered to maintain consistent orbital motion and pad flatness.
| Model(s) | OEM Part Number | Pad Density | Price (approx.) |
|---|---|---|---|
| BO5041, BO5031, BO5030 | 743081-8 | Rubber pad, 125mm | £8–11 |
| DBO180Z (cordless) | 743081-8 | Rubber pad, 125mm | £9–12 |
The standard replacement pad is 743081-8 (125mm), listed for BO5030, BO5031, BO5041 and DBO180. Most users need only the medium pad; buy the soft pad if you frequently sand mouldings or shaped work.
Makita Abrasives: Sanding Discs and Grits
Makita sells 125mm 8-hole hook-and-loop discs, such as P-43555 (80 grit).
Common Makita Disc Types
- Standard wood abrasive: Closed-coat, suitable for wood, MDF, and composite materials. Grits P60–P150 most common.
- Fine finish abrasive: Grits P180–P220 for final passes and veneers.
- Multi-grit assortments: 10-pack or 50-pack mixed-grit packs at good value.

Cross-Brand Compatibility: Makita vs DeWalt vs Bosch
This is the critical section if you’re considering switching brands or own sanders from multiple manufacturers.
Disc Compatibility (8-Hole Discs)
All standard 8-hole abrasive discs—regardless of brand—will physically fit any 8-hole pad. This includes:
- Makita discs on DeWalt or Bosch pads
- DeWalt discs on Makita pads
- Third-party brands (Mirka, 3M, Sia, etc.) on any brand’s pad
Why this works: 8-hole spacing is an industry standard. Hole diameter, spacing, and arrangement are identical across all brands for 8-hole systems.
However: dust extraction efficiency varies because hole positions don’t perfectly align with each sander’s dust ports. Use matched discs (Makita discs on Makita pad) for optimal dust capture.
Pad Compatibility (Physical Fit)
Important: pads are NOT interchangeable between brands, even though discs are.
| Brand | Pad Size (mm) | Mounting Type | Screw Hole Spacing | Compatible With |
|---|---|---|---|---|
| Makita BO50xx | 123 dia. pad / 125 dia. disc | Screw-in | Makita-specific | Makita only |
| DeWalt DWE6423 | 125 dia. pad | Four screws | DeWalt-specific | DeWalt only |
| Bosch PEX 125 | 125 dia. | Screw-in | Bosch-specific | Bosch only |
The bottom line: Discs are universal across 8-hole systems. Pads are brand-specific. If your Makita pad wears out, you must buy a Makita pad—you cannot use a DeWalt or Bosch pad as a direct replacement.
Makita Cordless Sanders: DBO180Z and 18V LXT Battery Compatibility
The DBO180Z is Makita‘s cordless random orbital sander, powered by 18V LXT batteries. It uses the same 125mm 8-hole pad as the corded models, making it a true drop-in corded/cordless option.
Battery Compatibility
The DBO180Z works with all Makita 18V LXT batteries:
- BL1840B: 4.0Ah
- BL1860B: 6.0Ah
For extended sanding sessions, a higher-capacity pack such as the BL1860B (6.0Ah) runs longer between charges; Makita does not publish a sanding runtime. Pair it with a second battery for all-day cordless work.

Frequently Asked Questions
Can I use DeWalt discs on my Makita sander?
Yes, absolutely. 8-hole discs are universal. A DeWalt or Bosch 125mm 8-hole disc will fit your Makita pad perfectly. Dust extraction will be slightly less optimised than with Makita discs (because hole positions may not align perfectly with Makita dust ports), but performance is still excellent.
How long does a Makita sanding pad last?
In a busy workshop (daily use), expect 50–100 hours before the hook-and-loop backing loses grip or the pad surface becomes uneven. In casual use (weekend work), a pad can last 1–2 years. Replace when discs no longer grip securely or the pad develops a concave surface.
Which grit should I use for different tasks?
P40–P60: Rough stock removal, paint stripping. P80–P120: General purpose, stock removal, smoothing. P150–P180: Fine finishing, veneers, final surface preparation. P220: Sealant/paint prep, ultra-fine finishing.
Is the cordless DBO180Z as powerful as the corded BO5041?
The corded BO5041 (300W) has no battery limit. The cordless DBO180Z (18V LXT) runs for as long as its battery lasts; Makita does not publish a sanding runtime, so a larger pack or a spare battery is the way to sand for longer.
Can I fit a Makita pad on a DeWalt sander?
No, pads are not interchangeable. Screw hole spacing is different between brands. You must use the original brand’s replacement pad. However, you can use 8-hole discs from any brand on any brand’s pad.
Where can I buy replacement Makita pads and discs?
Amazon, Screwfix and Toolstation list Makita pads; check stock and collection times locally. Specialist suppliers like Axminster carry premium alternatives like Mirka and Sia.
How we compile this guide
We cross-reference compatibility details against manufacturer specifications where available, official tool manuals, and the physical standards that govern fitment (bore sizes, arbor diameters, voltage platforms, connector types). We prioritise primary sources over retailer listings, flag anything we can’t confirm, and re-verify the data on a regular cycle. Where we give a buying recommendation, we tell you the reasoning — not just the link. More on our method →
